What This Utility Data Tells You

Gulf Power Co is a investor-owned utility operating in Florida under EIA identifier 7801. Customer count is not reported in the current EIA filing. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.

In 2021, the average Gulf Power Co customer experienced 74.4 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. SAIFI — the average number of outage events per customer — was 0.78 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 40.4 minutes — the gap between that figure and the headline 74.4 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 2 years of continuous reporting (2020–2021) for Gulf Power Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 1934.9 to 74.4 minutes over that window — a meaningful direction for prospective customers and regulators watching capital investment outcomes. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.

What is SAIDI without major event days?

SAIDI "without major event days" (SAIDI nMED) excludes outages caused by hurricanes, ice storms, and other catastrophic weather events. It better reflects day-to-day infrastructure reliability rather than vulnerability to extreme weather. Both standard SAIDI and SAIDI nMED are shown in the reliability trend table above.
